BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 455,160, dated June 30,1891. Application filed August 2'7, 1890. Serial No. 363,173. (Nomodel.)

off for smoothing the tops of the bricks and separating them from themud-die.

To this end my invention consists in certain features of constructionand combinations of parts, which will be hereinafter fully described,and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a vertical longitudinal section of the machine on the line 11 of Fig. 2. Fig.2

.is a broken plan view, partly in horizontal section; and Fig. 3 is avertical cross-section on the line 3 3 of Fig. 1.

The machine is provided with a vertical rectangular frame A, which has amud-box B, extending transversely across the top, and mounted on top ofthe machine-are the horizontally-movable slides O, which are adapted toclose over the opening to the mud-box and thus regulate the flow of mudinto the same. The mud-box is adapted to be arranged below an ordinarypug-mill, and extending across the mud-box is a partition B, having avertical perforation b therein adapted to receive a mast connecting withthe pug-mill in the ordinary way A die D is arranged to slideverticallyon the mud-box B, which is open at the bottom;

and the die is provided with inwardly-turned flanges or shoulders D, andis provided with transverse strips d, which divide the bottom opening ofthe die into spaces, each space cor responding in size to the size ofthe bricks to be pressed. The die D is provided at the ends withoutwardly-extendin g bars E, adapted to move vertically in theslideways' a, and

the outer ends of the bars are connected by the links 6 with the lovers6, which are mounted on opposite sides of the machine and have theirfree ends provided with weights F, which thus serve as counter-balancesto the die D and tend to press the die upwardly against the mud whichflows into it from the box B. v

A plunger G is arranged horizontally below the die D, from which on itsunder side projects a vertically-movable piston-rod G, the piston-rodand plunger being also provided with suitable braces G and the lowerportion of the piston-rod at the point 9 is cut away to make room forthe convex head of a treadle-lever H, as described below. Depending fromeach end of the plunger G are the guide-rods g, which move verticallythrough the perforated guides g which are attached to the cross-bar A ofthe frame A, and the plunger is thereby held so that it moves verticallyand with the necessary precision.

The treadle-lever His pivoted in the frame in front of the piston-rod G,the said lever having a convex head H, which is received by the cut-awayportion of the piston-rod, as described, and the lever is connected withthe lower end of the piston-rod byametallic strap h, which is fixed tothe upper portion of the lever and extends around the convex headthereof. The lever H is also provided with an upwardly-extending arm71/, having atthe end a weight h which, when the lever is depressed andthe piston-rod and plunger raised, acts as a counter-balance to theplunger and serves to prevent it from falling.

Extending horizontally through the machine on each side thereof arestrips J, which are fixed to the machine-frame and which are providedwith rolls j, which are pivoted thereon and which serve as tracks, andthe strips are arranged in such a mannerthat there will be just roombetween the tops of the rolls and the lower portions of the die D forthe inser- I tion of a pad K and a mold L, which is placed thereon. Thepads K used in connection with this machine are fiat, and are adapted tocarry the molds L. The length of the pads corresponds to the distancebetween the two roller-tracks extending through the machine, and thepads have depending flanges K at the ends, which ride upon the rolls j.The molds L are the ordinary bottomless molds and need no detaileddescription.

Extending forwardly from the plunger G are the horizontal and parallelrods M, which are connected at the ends by a cross-bar M, and mounted onthe rod so as to slide thereon is a slide N, having depending flanges N,which slide upon the rods M. The central portion of the slide is cutaway, as best shown in Fig. 2, to form the handle it, and on each end ofthe slide near the rear portion thereof are vertical studs 01, to thetop of which are pivoted the arms 0. The slide N has lugs 01 projectingfrom its rear edge and adapted to impinge upon the molds L when theslide is pushed rearwardly and hold the molds in place.

The arms 0 are connected at their rear ends by a wire P, adapted to cutthe mud, as described below, and the front ends of the arms areconnected by a rod P, having suitable nuts at each end, and by turningthe nuts the arms 0 may be actuated and the wireP tightened or loosened.Then the slide N is in the front portion of the machine,asshown in Fig.2, the rod P is depressed and the wire P raised by means of the springsm, which are rearwardly above the slide N, so as to auto maticallyengage the rod? when the slide is moved forward. hen the slide is pushedinto the machine, the springs g, which are attached to the slide andnormally press upward, engage the rod P as it passes from beneath thesprings in and push the rodnpward, so that the wire Pwill be forceddownward and will press upon the top of a mold, the position of the moldbeing indicated by dotted lines in Fig. 1.

The machine is operated as follows: The mud is fed into the mud-box Bfrom the pugmill. The lever H is raised so as to throw the plunger Gdown. A pad K is placed upon the rolls j. A mold L is placed upon thepad in the rear of the slide N, as indicated by the dotted lines in Fig.1, and the slide is pushed rearwardly, thus forcing the pad andmoldbeneath the die D; and it will be observed that the wire P willpress upon the top of the mold and will be forced through between thetop of the mold and the bottom of the die D. The lever H is thenactuated so as to raise the plunger G, thus raising the mold and forcingthe mud firmly into it. The slide N is withdrawn, and the wire P,passing between the mold and the die,cuts the mud smoothly, and thecounter-weight F holds the die from dropping back upon the mold. Anotherpad is then placed behind the slide N in the manner already described,and the operation is repeated, the last pad pushing the first pad andmold from beneath the die to the rear of the machine, and from thencethe mold may be taken and the brick formed therein tiered up in theusual manner.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. In a brick-machine, the combination, withthe supporting-frame and a mud-box, of a die provided withoutwardly-extending bars working in guideways in the frame, weightedlevers pivoted to the frame, and links c011- necting the levers with thebars of the die, substantially as herein shown and described.

2. A brick-machine having a mud-box in the upper part thereof, a diearranged to move vertically upon' the mud-box, roller-tracks extendinghorizontally through the machine, and a vertically-movable plungerarranged between the tracks and aligning with the mud-box and die,substantially as described.

3. In a brick-machine, the combination, with the die, the rollertracks,and the moldreceiving pad mounted thereon, of a slide arranged to movewith the pad and mold and a spring-pressed frame mounted' on the slideand provided with a wire adapted to press upon the top of a mold,substantially as de scribed.

at. In a brick-machine, the mold-carrying pad having a fiat base anddepending end flanges, substantially as described. fixed to thecross-bar M and which extends 5. In a brick-machine, the combination,

with the die, the horizontally-movable moldcarrying pad thereon, of aslide arranged to move with the pad, arms pivoted on opposite ends ofthe slide, the said arms being connected at the rear end by a wire andat the front end by an adjustable rod, springs fixed to a support in thefrontof the machine and adapted to press downward upon the adjustablerod, and springs fixed to the top of the slide and adapted to pressupward upon the said rod, substantially as described.

6. A brick-machine comprising a frame, a mud-box in the top thereof, adie adaptedto move vertically on the mud-box and having an openingthrough the bottom thereof, a track extending horizontally through theframe, a verticallyhnovable plunger aligning with the mud-box and die,rods extending horizontally from the front of the plunger, a slidemounted, on the rods, and a springpressed frame pivoted on the slidesand carrying at its rear end a wire to pass beneath the die,substantially as described.

7. The combination, with the plunger and the piston-rod connectedtherewith, said rod being cut away at its lower portion, as shown, of apivoted lever having a convex headcoutiguous to the cut-away portion ofthe pistonrod, a metallic strap fixed to the lever and extending oversaid convex head to the lower end of the piston-rod, and a weighted armfixed to the lever and extending upwardly therefrom, substantially asdescribed.
